What were your best nine Instagram photos from 2017?

You might have noticed a new end-of-year trend on Instagram the past few days. If so, you can thank 2017bestnine.com, a website that lets you automatically collect and collage your most-liked photos of 2017.

Best Nine has been around for a while, so many of you may be familiar with the tool already. But for those of you who are new to that Best Nine game, here’s how it works.

First of all, your Instagram profile must be public for this to work, so if you have it set to private, quickly switch it to public to allow Best Nine to get in there and do its magic. Once your profile is public, head to 2017 Best Nine and input your Instagram ID.

After a few seconds (or minutes, depending on traffic to the site), the Best Nine service will offer you options for your final collaged photo that includes your best nine photos from 2017.

The ‘original version’ includes a caption that says “Thank you for your likes!” with the hashtag #2017bestnine at the top. You can also choose the photo only version or check out your best nine from 2016.
